Interrupt and Trap Functions

The C166 architecture supports several mechanisms for fast and flexible response to
service requests that can be generated from various sources either by the CPU itself or
external, i.e. peripherals connected to the XBUS or the PD bus.

These mechanisms include:

Normal Interrupt Processing

The CPU temporarily suspends the current program execution and branches to an
interrupt service routine in order to service an interrupt requesting device. The current
program status (IP, PSW, also CSP in segmentation mode) is saved on the internal
system stack. A prioritization scheme with 16 priority levels allows the user to specify the
order in which multiple interrupt requests are to be handled.

Interrupt Processing via the Peripheral Event Controller (PEC)

A faster alternative to normal software controlled interrupt processing is to service an
interrupt requesting device with the integrated Peripheral Event Controller (PEC).
Triggered by an interrupt request, the PEC performs a single word or byte data transfer
between any two locations in the whole memory space through one of nine
programmable PEC Service Channels. During a PEC transfer the normal program
execution of the CPU is halted for just 1 instruction cycle. No internal program status
information needs to be saved. The same prioritization scheme is used for PEC service
as for normal interrupt processing. PEC transfers share the 2 highest priority levels.

M2 enhances the functionalities of the original C166 PEC with the following features:

• PEC range extended to the entire memory space,
• new chaining mechanism between pairs of PEC channels.

Trap Functions

Trap functions are activated in response to special conditions that occur during the
execution of instructions. Several hardware trap functions are provided for handling
erroneous conditions and exceptions that arise during the execution of an instruction.
Hardware traps always have highest priority and cause immediate system reaction. The
software trap function is invoked by the TRAP instruction, which generates a software
interrupt for a specified interrupt vector. For all types of traps the current program status
is saved on the system stack.
